How Many Keys Does a Piano Have ?
88 keys: 52 white keys and 36 black keys (The Bösendorfer Imperial – between US$256,000 and $560,000 in the U.S. – features 97 keys).
What is the Difference Between the White Keys and the Black Keys ?
The white keys play the natural notes A, B, C, D, E, F, G.
The black keys are used to play the sharp notes and the flat notes.
Why There is Only Five Black Keys Rather Than Seven?
Because there is a full tone between C and D, D and E, F and G, G and A, A and B, but only a semitone between the E and F, and only a semitone between B and C. The black keys are used to divide a full tone in two semitones.
So, a tone is the interval between two white keys separated by a black key. A semitone is the interval between two white keys without being separated by a black key or between a white key and a black key.
So the Number of Piano Notes is 12…
Yes! A music keyboard (piano, harpsichord, synthesizers, organ) can play the 12 music notes of the Western musical scale.
… or 88 ?
You can say there are 12 notes and 88 keys: each music note is available many times with different frequencies (pitch).
The distance between two notes with the same name but different frequencies is called an octave (from Ancient Greek ὀκτώ – oktṓ – meaning height). For example: C1 D2 E3 F4 G5 A6 B7 C8.
A piano has 7 octaves 1/4.
The white keys play C D E F G A B (DO RE MI FA SOL LA SI). The black keys play C#/Db, D#/Eb, F#/Gb, G#/Ab, A#/Bb (DO#/REb, RE#/MIb, FA#/SOLb, SOL#/LAb, LA#/SIb).
Remark: the black keys and the white keys are sometimes reversed on a harpsichord.
